Term | Definition |
---|---|
Inorganic | no carbon |
Acids | release hydrogen ions when dissolved in water(0-6 on the pH scale) |
Bases | release hydroxide ions when dissolved in water(8-14 on the pH scale) |
pH Scale | a way to measure how acidic or basic a chemical is |
Organic | contains carbon as the major component |
Carbohydrates | sugars! immediate energy source |
Monosaccharides | simple sugars |
Disaccharides | double sugars formed by 2 monosaccharides joining together by dehydration synthesis. (protein key) |
Polysaccharides | polymers (long branching chains of linked monosaccharides) linked together by dehydration synthesis. (large & fairly insoluble which make them ideal storage products) |
Hydrophilic | likes water |
Hydrophobic | dislike waters |
Neutral Fats - Triglycerides | long term energy storage no oxygen does not dissolve in water |
Phospholipids | cell membrane structure dissolves in water |
Steroids | Hormones made my cholesterol |
Proteins | structure, enzymes, regulation |
Amino Acids | building blocks of proteins (2 types: fibrous and globular) |
Peptide Bond | primary structure of proteins |
Isotonic Solutions | same solution |
Hypotonic Solutions | more water |
Hypertonic Solutions | less water |
Mitosis | cell division |
Cell Physiology | DNA makes RNA RNA makes Protein |
DNA | Deoxyribose Nucleic Acid (hereditary material) |
RNA | Ribose Nucleic Acid (controls protein structure) |
ATP | Adenosine Tri Phosphate (energy molecule) |
Diffusion | the spreading of particles from an area of higher concentration to an area of lower concentration |
Osmosis | diffusion of water |
Cytokinesis | cytoplasm division |
